Package: ocaml-mingw-w64 Version: 4.01.0~20140328-1+b2 Severity: important Trying to compile a "custome" bytecode executable with x86_64-w64-mingw32-ocamlc or i686-w64-mingw32-ocamlc fail at link time.
The following commands cat > main.ml <<EOF print_endline "Hello world" EOF x86_64-w64-mingw32-ocamlc main.ml -o main.exe -custom lead to these errors ** Cannot resolve symbols for descriptor object: WSACleanup WSAStartup connect gethostbyname getsockopt htons inet_addr setsockopt socket File "main.ml", line 1: Error: Error while building custom runtime system Instead by using this command x86_64-w64-mingw32-ocamlc main.ml -o main.exe -custom -cclib -lws2_32 the executable is correctly created (tested using wine). As far as I can tell, -lws2_32 should be automatically added by ocamlc while creating custom bytecode executable. The same issue applies while linking a shared library using -output-obj option x86_64-w64-mingw32-ocamlc main.ml -output-obj -o main.so ** Cannot resolve symbols for descriptor object: WSACleanup WSAStartup connect gethostbyname getsockopt htons inet_addr setsockopt socket File "main.ml", line 1: Error: Error while building custom runtime system -- System Information: Debian Release: 9.0 APT prefers unstable APT policy: (500, 'unstable'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.9.0-3-amd64 (SMP w/8 CPU cores) Locale: LANG=it_IT.UTF-8, LC_CTYPE=it_IT.UTF-8 (charmap=UTF-8), LANGUAGE=it_IT.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Init: systemd (via /run/systemd/system) Versions of packages ocaml-mingw-w64 depends on: ii ocaml-mingw-w64-i686 4.01.0~20140328-1+b2 ii ocaml-mingw-w64-x86-64 4.01.0~20140328-1+b2 ocaml-mingw-w64 recommends no packages. ocaml-mingw-w64 suggests no packages. -- no debconf information
